Question

the perimeter of the base of a cylinder is 24 cm then height is 8 cm then the curved surface area is​

Answer 1

Step-by-step explanation:

curved surface area with radius r and height h is

Curved surface area=2π rh (1)

As height=h=8cm

Perimeter of base=2πr

24 cm=2πr

r=24/2πcm (2)

Put the value of radius from (2) into (1)

Curved surface area=2π(24/2π)8 cm.cm

Curved surface area= 192cm²
